OK folk, I am sure that the collective knowledge will have a quick answer to the question.

In short, I had an award reservation (pre-dev) with a BRU-IAD flight on SN which got cancelled (they stopped flying the route in the winter). I have changed the flights (a long story there, they originally charged the new price for it and then changed it back to the hold price).

However, when I check the e-ticket on Saudi web site half of the flights show "Airport Control" and not "Open for use".

Should I be worried?

(The complete trip is IAD-ARN-FCO-X-TLV-VIE-ZRH-YUL-DCA, used to be IAD-ARN-FCO-X-TLV-VIE-BRU-IAD)
